To all whom 'it may concern:

Be it known that I, FREDERICK FRANKLIN FIELD, acitizen of the United States,resid-' ing at Lakewood, town of vVVai-Wick, in the county of Kent and State of Rhode Island,

have invented' a 'new and useful Improve-A ment in Valve Mechanisms, of which the' following is a specification.`

This invention-has reference to an improvement in valves and more particularly to an improvement in valve mechanisms for I high pressure faucets and the like.

. In the use of faucets and the like, usually as heretofore constructed for high pressure water systems, great trouble has been caused by the valve niechanisniof the'faucet' ham- {niering under thepressure of .the water,

which is annoying and causes' the valve mechanism to wear outo'uickly. 'These valve mechanisms or parts are usually secured in the faucet by screw-threads and gaskets or similar construction,l which increases .thel

cost of manufacturing, are liableto lleak andY generally canse trouble in removing the valve mechanism for repairs or renewal of The object of my .invention is to improve the construction of f valve mechanisms for high pressure faucets and the like, whereby the following. undesirable features are eliminated'; wat e1' hammering of the valve, screwthreads for securing the valvev mechanism in the faucet, and gaskets or packing intermediate the valve mechanism and the faucet, and the cost of Vmanui'acturing greatly reduced.'

A further object of my invention is to providea valve mechanism having a charnber under 'the valve head,` the air-,in said chamber acting as a cushion to the valve head when it is forced inwardly to open the valve, and tl-c valve being slowly closed by the gradual inflow of air around thc vvalve head andA into the chamber; under itaud by the water pressure.

My invention consists'in the peculiar and novel construction 'of a valve mechanism forliigli'vprcssure faucet-s and the like, said valve mechanism having details of construction, as will be more fully sct forth hereinafter and claimed.

Figure 1. is a vertical sectional view taken longitudinally through the faucet with the valve mechanism in `the. closed position. Fig. 2. is a verl-ical sectional view taken on Y line 2. 2. of F ig. 1. with theval've mechanism in the open position. Fig. 3. is an ennlargedend view ofthe valve'seatgineinber looking attlie valve seat end of the same. Fig. (l. is an enlarged upper'end View of ,the

plunger valve head member. Fig. 5. isfan"l enlarged vertical sectional View ofthe ,valve seat member, taken on line 5.5. of Fig'. 3. Fig. 6. is an enlarged vertical sectional view through the vacuum chamber member, and

In the drawings SL indicatesa faucetebody of conventional exterior form, 9..:th'e separable .top of the body, 10. a tubular. post Vin the topp,` 11.-A the valveA stein, 12. the/.valve seat member, the vacuum chamber-inein- .ber, 14. the plungervalve head member, 1 5.

a. Acoiled springand n39. acliainber understhe` valvc-headmemhcr. The faucet bodye-Sahas an enlarged central chamber 1.6. anVA .inlet duct 17. having a funnel-shape inner-fend 18; yopening into-the central' chamber 16. and forming a circular wedgeshape seat for the vacuumchamber member 13., an outlet duct 19. on the side andan open internally screwthreaded. upper end- 20. as shownv in Figs. 1 and 2. 'The separable' top 9. of the body 'has a screw-threaded lower end 21. which screws into the upperendi'20. of the body 8.

a downwardly turned Aannular lip-22. a nutshaped upper end 23. and an internally screw-threaded central hole 24. vThe lower end 21. is fiat on the bottom', as shown in Fig. 2.' The .tubular post 10. has the nut shape upper end 25'. and is screwthreitled into the central hole `24. in the-top 9. as shown in Fig. 2; The valve stem .11. has a sliding fit in the tubular, post 10., an enlarged lower end 26. forming a stop and the usual head 2?..0n the, upper end, as shown in Fig. 2. The valve scat member 12.'V is cylindrical. in forni and -has an open upper end 28. the side openings 29. 29.,.an inverted cone-shape 'lower portion 30. anda circular valve seat 31. surrounding an inlet opening 32. in the-lower end of the meiuber,.a s shown in Fig.` 5. The vacuum chamber member 13. has a cylindrical body 33.closedI A.

at the lower end, a funnel-shapeopen'upperA end 34. and a. sei-ics of holes 35. 35. .in the body adjacent the'upper end. These holes body 33. of the vacuum cl'iainber irieiuber.

13., a; packing washer 36. recessed into the top, a stemv 37. screw-threaded into the head and shouldered to hold thepacking washer in the head and a recess 38. in the bottom -for th'e coiled spring 15. as shown in Fig. 7.

When assembled, the screwing down of 'the top 9. against the upper end v28. of the valve seatmember 12. forces the cone-shape lower end of the valve seat member into the funnel-shape'upper end of the vacuum chamber member 13. which in turn is forced or .wedged into' the funnel-shape inner end 18. or seat of the linlet duct 17. *thereby firmly securing the valve mechanism in place and forming a water tight joint at.

this point, without the use of screw-threads, gaskets or packinff. lVith the valve mechanism in the closed position, the valve head 14. en ages with the valve seat 31. and closes t e inlet opening 32. in the valve seat member 12. and also closes the holes 3 5.' 35. in the side of the vacuum chamber member 13. The seating of the valve head 14 on the valve seat 31 is accomplished by the 25.

coiled spring 15, the action of which is retarded on account-ofthe vacuum formed in thechamber below the valve head 14. in the vacuum chamber 'member 13, or the spring 1 5. may be eliminated and the gradually increasm f volume -of the air in the' said chamber elow the valve head. would then I act to seat the valve, assisted by the pressure of the 'waterf A downward movement of the head .27.forces the valve s'temll. downward, which engaging with the stenr37. on y'the valve head 14. forces the valve'head '14.

13. and opens the holes 35. 35. in theside' of 1:. the member 13. The water now has 'affree pas- 40 sage through the inletduct 17., the holes 35.

35. 4inthe vacuum chamber member 13. the :in let opening 32.-. and side openings29. 29.

in the'valve seat member, the centralchamber 16. and out through the outlet/duct 19.

The entire valve mechanism may be easilyV and quickly removed, by, unscrewing Athe top-9. and with a tool grasping the end of `the stem 37.0n the valvehead 14. and pull- -infr the samefout of the body of the faucet.

t is evident that the construction of the valve mechanism could be varied without ,1.- ,Hayng .1511's described my invention,
